Abstract

Dynamic modelling and simulation offers a way to investigate the transient behavior of thermal energy storage (TES) systems. Most modelling work presented in literature focuses only to sub-processes of a TES facility, especially, if the comparison against experimental data is included. In this study, we combine experimental and computational work, and aim at modelling and investigating the whole TES system. We share experiences gained and discuss results, including the experiments planning, modelling scope, measurement uncertainty, heat exchange, heat losses, calibration and validation.Dynamic modelling and simulation offers a way to investigate the transient behavior of thermal energy storage (TES) systems. Most modelling work presented in literature focuses only to sub-processes of a TES facility, especially, if the comparison against experimental data is included. In this study, we combine experimental and computational work, and aim at modelling and investigating the whole TES system. We share experiences gained and discuss results, including the experiments planning, modelling scope, measurement uncertainty, heat exchange, heat losses, calibration and validation.

蓄热装置的实验与理论研究展望

动态建模和仿真为研究热储能系统的瞬态行为提供了一种方法。文献中提出的大多数建模工作只关注TES设施的子过程，特别是如果与实验数据进行比较。在本研究中，我们将实验和计算相结合，旨在对整个TES系统进行建模和研究。我们分享经验并讨论结果，包括实验计划、建模范围、测量不确定度、热交换、热损失、校准和验证。动态建模和仿真为研究热储能系统的瞬态行为提供了一种方法。文献中提出的大多数建模工作只关注TES设施的子过程，特别是如果与实验数据进行比较。在本研究中，我们将实验和计算相结合，旨在对整个TES系统进行建模和研究。我们分享经验并讨论结果，包括实验计划、建模范围、测量不确定度、热交换、热损失、校准和验证。
